Enhancing perinatal outcome evaluation with the Composite Adverse Perinatal Outcome (CAPO) index: A modified Delphi...

Area of Science:

• Obstetrics and Gynecology
• Neonatology
• Public Health

Background:

• The Weighted Adverse Outcome Score (WAOS) is a tool for measuring perinatal outcomes.
• There is a need for a more comprehensive measurement tool for perinatal health.

Purpose of the Study:

• To develop an extended perinatal outcomes measurement tool by enhancing the Weighted Adverse Outcome Score (WAOS).
• To create the Composite Adverse Perinatal Outcome (CAPO) index.

Main Methods:

• A modified e-Delphi survey was conducted with 29 experts (obstetricians, neonatologists, scientists, policymakers).
• Experts rated the importance, evidence, and feasibility of proposed WAOS extension components.
• Severity scores were assigned, and consensus was reached on additional outcomes.

Main Results:

• 13 additional outcomes were identified and integrated with the original WAOS.
• The final Composite Adverse Perinatal Outcome (CAPO) index includes 7 maternal and 6 neonatal outcomes.
• Each outcome received a severity score, contributing to a comprehensive evaluation.

Conclusions:

• The Composite Adverse Perinatal Outcome (CAPO) index was successfully developed, encompassing 23 maternal and neonatal outcomes.
• The CAPO index offers a comprehensive approach to evaluating perinatal health.
• Further clinical and research validation of the CAPO index is recommended.
